Nice one. like it. though i want to tell you of some of my wish related to your story.
1. Lemon is a waste of words to me. A simple romantic scene should be enough.
2. I wish Naruto could be a little bit more matured.
3. And Juubi could be more ferocious and blood lusty.
4. I think Obito lost his one portion of body in third ninja world war.
5. And Only Obito has a unique kamui technique like Shisui had Kotoatsukami.
6. If though Obito here is survived then who'll be the masked man that has the ability to create own pocket dimension like Tobi or Obito had.
7. You may give Naruto a stronger version of Sharingan-Rinnegan duo with for holy power.
8. And personally i presume, Naruto should display Juubi's those complicated while in Bijuu state instead of Black slitted eyes.

I know it's your fic.
You have in-dependency to change anything you want.
But i just merely pointed some things for your considerations.
